I was wondering why cytokines, and lymphokines for that matter, are not
usually considered as a functional part of cell-to-cell communication, at
least not in the textbooks I have used. Is the distinction between
hormones and -kines merely taxonomic? Or is there a different mechanism
for -kines, for instance no secondary messangers or specific receptors as
there are for hormones?
I hope some one will reply as I am very curious! Thanks in advance. :-)
